Improvement in tailing-elevators for separators

The Schedule 'referred to in these Lettere Patent and malring'part o thesame.

To all 'whom it may concern:

Be it known thatlgnrnon B. FARQUHAR, of York, in the county of York andStateoi Pennsylvania, have invented new and useful Improvements in.Tailing-Elevatois for con. .u ,5 material known as tailings from thefan back to the thrasher of a graiuseparator; and I do. hereby declarethat the fol- 4lowing is a full, clear, audeiact description of the"construction and operation oi the same, reference being had to theannexed drawings making part of this specification, in fWhichl-- i,Figures I and 3 are a top viei'v or plan, and

Figure 2, a vertical section. My improvements. are divided i intovseveral parts, which may be used separately or in connection, and

which' niay be applied vto maohineslmfWsimilar class heretofore in use.v

The nature and novelty of myinvention consists inthe arrangementoi'ahelixV (or suhall'screw) in a trough or pipe, for. conveying theWhitecaps and uuthrashed heads of grain (technically styled tailings)from the fanback to the thrasher of a grain-separator, and., by means ofa screen in bottom-of said trough, separating therefrom the cookle anddirt.

To enable others vskilled in the art to make and use mynvention, I willproceed todeseribe its construction and operation.

T elevating-trough A H 4rests at one end near the' an, the other being,rraised suciently to discharge through spout D into the thrasher.

y The tailings may be delivered from the fan into the elevator in themslm-1 manner by a shaking spout, but this arrangement being verytemporary and liable to `choke in Wet grain, I prefer using; anothertrough and helix, as shown in iig. 3, opening into the elevator at rightangles, thus obviating the possibility of choking. The helices arereadily formed by winding half-inch round'or square iron over arevolving mandrel in -an ordinary enginedathe, allowing one .end toextend out far enough to receive the-flliving-pulley C.

The power required to operate it is scarcely appl-e eiable. The tailingsare carried up inside of the coil, and are discharged evenly into thethrasher. Most of the cockie, chess, and other impurities pass throughthe screen F into a box below, the'screen being-kept clear and openbythe revolving helix or screw rubbing over it'.-

Nine out of every ten grain-separators in use are provided withtolling-elevators made of a series oi' buckets o1: blocks fastened torevolving belt, and

they are the most troublesome part of the machine,

from liability to get ont oi' order and choke up.

N ow, it will be readily seen that these objections are-entirely'overoome by my improvement, since the iron coil will last alifetime, and cannot get out of order or choke up, besides costing lessthan halt' vas much to make as the old style.

I may add, in conclusion, that I have thoroughly tested its operationsduring the pastseasonv upon a number of machines, and the universaltestimony oi experienced thrashers encourages me to present my claimsfor what I deem as novel as they have been proved useful.

i I do not claim the several parts.herein shown, nor

any general combination of the. same; but4 Nhat I do olaimis- Thearrangement of' the trough A and helix -15 with trough H, helix B,screen F, and spout I), as herein described and for the purposes setforth.
